Cassava:
Crop ReportThroughout history there have been many important crops that have been detrimental to societies, but in recent history the Cassava plant has been one of the most important to people in Asia, South America, and Africa. To people in America, Cassava may be unknown, but its importance needs to be recognized. The characteristics of Cassava to grow in non-fertile places, have good nutrional value and also supply some of a countries economy make it unvalued around the world. Cassava also known as Yuca, Tapioca, or Manioc is beginning to be used in greater force around the world because of its convenient characteristics.

Cassava or Manicot Esculenta originated in Brazil and Paraguay with west, central Brazil having wild populations of the Cassava subspecies flabellifolia, shown to be the progenitor of domesticated cassava. It was then first likely domesticated no more than 10,000 years BP. The oldest direct evidence of cassava cultivation comes from an old Maya site, in El Salvador. Cassava became a staple food of the native populations of northern South America, southern Mesoamerica, and the Caribbean by the time of the Spanish conquest. Its cultivation was continued by the colonial Portuguese and Spanish. Cassava was a staple food for pre-Columbian peoples in the Americas. This is remarkable, because cassava roots are bitter and deadly poisonous if eaten raw. Also, Cassava was portrayed in indigenous art, which showed how important Cassava was in the culture of these early civilizations. With the change in times came a change in Cassava.

Today’s Cassava is extensively cultivated as an annual crop in tropical and subtropical regions for its edible starchy tuberous root. It also serves as a major source of carbohydrates. The people that use and grow cassava in today’s society first boil and shed the root of its skin, whereas the pre-Colombian era just boiled and used cassava with the outer layer still intact. This is remarkable because the...

I. Overview
Cassava (Manihot esculenta Crantz, Euphorbiaceae, Dicotyledons) is the sixth most important crop after wheat, rice, maize, potato and barley and is the primary staple for more than 800 million people in the world, mostly in the poorest tropical countries. The term cassava is most likely derived from the Arawak word for bread, casavi or cazabi, and the term manioc from the Tupi word maniot, which French explorers converted to manioc. Cassava plays an essential food security role because its matured edible roots can be left in the ground for up to 36 months. The crop therefore represents a household food bank that can be drawn on when adverse climatic conditions limit the availability of other foods. The variety of foods that are made from the roots and the nutritious leaves are reasons why cassava cultivation is expanding worldwide (Lebot V, 2009)
Cassava is one of plants which it easily to adapt in tropical and subtropical countries of Asia. environment. Indonesia is the major producing in Asia, Thailand, india and China are followed, So, it is easy to see cassava every province. Thins plant...

...support for the reason that there’s a lot of things you need to accomplished in college which needs money.
This factor has greatly affected to the students because it will go to the point that they can’t spend to buy things for their own interest. As what we noticed today, commercial products are getting expensive which more of us can’t afford and one of this is the body powder product either we admit it or not we want this things as a student.
This factor gives us an idea to investigate a powder which is affordable but applicable to use to the body which we just not only for having it but to help and gives contribution to our mother Earth as it is environmental friendly product which is made from the extract of Manihot Esculenta ( cassava) which undergo through traditional processes.
Having this product is not only best used as an alternative from the commercial body powder and saving the planet Earth but to help us moisture our dry and rough skin as one of the skin problem that the students experienced from too much exposure from the heat of the sun.
Based on our experimentation, we conclude that the body powder made from Manihot Esculenta is effective to use in the body which helps moisturize our skin from dryness and roughness.

Abstract
The cassava mealybug is an important pest which can cause a lot of damages to the cassava crop and lead vital problems for the African population. Some methods of control can be used to try to eradicate this pest like classical biological control, breeding resistant varieties or cultural control. However, the more efficient method to control the mealybug is the biological control with a natural enemy of the pest: a parasitoid named Epidinocarsis lopezi. This introduction of this parasitoid in some countries of Africa was one of the best success ever seen in the world in classical biological control.
Introduction
Cassava (Manihot esculenta) is the staple food of about 200 million Africans with a huge productivity of about 200 million tons per year. It is an exotic plant which was imported from South America in sixteenth century and an emergency food reserve in a lot of arid zone in Africa (Dent, D. 2000).
This crop had remained relatively pest free until the introduction of the Phenacoccus manihoti. This pest can destroy the cassava plantation, and causes a lot of damage on the plant. It reproduces very quickly and its proliferation leads serious problems for Africans (food production, health).

Introduction
The cassava (Manihot Utilissima), that is extensively cultivated as an annual crop for its edible starchy tuberous root, a major source of carbohydrates. The cassava root is long and tapered, with a firm homogeneous flesh encased in a detachable rind. In experiments, cassava yielded two to three times as much carbohydrate for fuel ethanol production (Comis, 2008).
Ethanol production from fresh cassava roots using a low-temperature process was evaluated on a pilot-plant scale. The application of low-temperature cooking to cassava starch followed by a dual enzyme action resulted in an ethanol yield comparable to that of a traditional high-temperature cooking process. Pressurized distillation gave a satisfactory recovery efficiency of ethanol but was slightly lower than that obtained from atmospheric pressure distillation. Over 40% of the normal steam consumption was saved by adopting the low-temperature cooking and pressurized distillation systems in the cassava-to-ethanol process. The yield of anhydrous ethanol varied with the starch content in fresh cassava roots and was in the range of 185 to 200 litres per tonne (Atthasampunna et.al, 2009).
As strengthen by Guindo, 2013, the world has evolved into a place where convenience is taken as a one of the major reasons why technology is at its peak in its continuous and countless innovations. These...

...Title: Cassava starch as an effective component for Ideal Biodegradable Plastic
Proponent: Zhaira Morysette L. Maco, III-Narra student
Introduction:
Inventions have evolved and continue to evolve such that after several years of study, research and experimentation reach great developments. With continuing efforts to investigate the constituents of Philippine plants, we have pursued investigation of starch of the cassava plant (Manihot esculenta).Cassava tubers were gathered, ground and squeezed to extract starch.
Cassava (Manihot esculenta), also called manioc, tapioca or yuca, is one of the most important food crops in the humid tropics, being particularly suited to conditions of low nutrient availability and able to survive drought (Burrell, 2003). The plant grows to a height of 1 to 3 m and several roots may be found on each plant. Although cassava leaves are sometimes consumed, the major harvested organ is the tuber, which is actually a swollen root. The plant is propagated mostly from stem cuttings. A major limitation of cassava production is the rapid post harvest deterioration of its roots which usually prevents their storage in the fresh state for more than a few days (Okezie and Kosikowski, 1982).
Cassava ranks very high among crops that convert the greatest amount of solar energy into soluble carbohydrates per unit of area. Among the starchy staples,...
